| 6001b Rm{William Robotham - Chief Engineer}/Wst.4/AP. 16th April 1937 Messrs K.L.G. Sparking Plugs Ltd., Putney Vale, LONDON S.W.15. Dear Sirs, K.L.G. type FE.30.X. Sparking Plugs. It has been noticed that the small brass adaptors screwed on to the terminal thread of the above sparking plugs are not entirely suitable for use with our spring-on type of moulded bakelite plug terminal on the Phantom III. chassis. It has been suggested that a parallel sleeve of the same external diameter as the one now being used and with ridges cut circumferentially similar to an ordinary coarse thread would be more suitable. We should like you to make up one or two of these adaptors to try with our terminals. Yours faithfully, FOR ROLLS-ROYCE LTD. | ||
